Some Things really Bug Me...

Social Media is all awash with people freaking out about drops or proposed drops of insects from planes or helicopters. Some have claimed it’s a conspiracy to infect millions of people with the next “new disease”. The three basic creatures (ticks are not insects) that people have been worrying about are: mosquitoes, ticks, and now screw flies.

There are two things to remember when reading about insect drops.

#1 many of these sites are just trying to get people to read their content because the more visitors they get, the more they get paid. So of course controversial is the go-to content. Because it’s technically their opinion, they do not have to substantiate what they say.

#2 Dropping serialized male insects to reduce populations is not new. It has been used since the 1950s. The screw worm was eradicated from the US using the technique. The recent new occurrences are basically because they haven’t kept up with it.

The basic idea for sterilized insect releases to control pests or diseases was conceived by E. F. Knipling (https://ipmworld.umn.edu/bartlett) in 1937. He used x-rays (later gamma rays) to cause sterility in male insects. It has been used around the world on a variety of beetles, flies, and mosquitoes to eradicate diseases and pests on fruits and vegetables. It is a tried and true method of control. In most species, especially mosquitoes and ticks, it is the female vector that carries the disease. The males do not feed on blood, They drink plant juices. Virtually all the released insects or other vectors are all male. So bokes of ticks dropped from planes (again not a new thing) are not feeding on other animals, they are just not reproducing. Many insects and other creatures mate only once so if it mates with a sterile male – no offspring.

Like anything, it can have issues. It is important to make sure that the insects released are truly sterilized.  One benefit is that it needs no insecticide so no resistance and no poisoning the environment with toxic chemicals. All in all, one of the better successes of applied science.

I hope this helps calms some fears for those that can’t resist scrolling. For more in depth information try this site. https://www.iaea.org/topics/sterile-insect-technique
